Abstract
A split T-shaped pipe serving as a housing device and comprising: an annular case body that has a split part in at least one location in the circumferential direction, and that surrounds the outer circumferential surface of a water pipe in a sealed state with a seal material therebetween; and fasteners for tightening the split part, thereby joining a plurality of split pieces constituting the case body. Joining surfaces are provided at the circumferential end portions of the split pieces, and protrusions protruding along the circumferential direction are formed on the joining surfaces but only at both end portions of the case body in the pipe axis direction of the water pipe.
Claims10
A housing device comprising:
- an annular case having a split portion at at least one location in a circumferential direction and being configured to enclose an outer circumferential surface of a fluid pipe in a sealed state by way of sealing material, said annular case further comprising a projection which protrudes toward the exterior in a pipe axial direction of the fluid pipe at both end of the annular case;
- restraint fixtures;
- a clamp comprising a plurality of clamping bolts inserted through clamping bolt holes, said clamp being configured to cause the split portion to be joined when the plurality of the clamping bolts are tightened;
- and
- adjustment bolt holes configured such that respective adjustment bolts inserted therethrough press against the outer circumferential surface of the fluid pipe at either end of the case;
- wherein the projection comprises a pair of protrusion segments formed in such fashion as to protrude in the circumferential direction, only at locations on joint surfaces provided at ends in the circumferential direction of the annular case that are at either end, in a pipe axial direction of the fluid pipe, of the annular case,
- wherein the pair of protrusion segments is not formed within a region toward an interior in the pipe axial direction from the bolt holes,
- wherein each restraint fixture is configured to overhang and encircle a respective projections at each end of the annular case.
